LNG (Liquefied Natural Gas) storage tanks are specialized equipment used to store liquefied natural gas.
The basic equipment of LNG filling stations includes storage tanks, vaporizers, pressurizing equipment, filling machines, metering systems, control systems, safety systems, cooling systems, emission treatment systems and auxiliary facilities.
Regular maintenance and inspection of LNG tanks is very important
Temperature and pressure monitoring: Maintain real-time monitoring of the temperature and pressure inside the tank to ensure that LNG is always within the designed safety range.
Vacuum insulation of LNG (liquefied natural gas) tanks is an efficient thermal insulation technology that ensures a low temperature environment inside the tank.
LNG vaporizer (liquefied natural gas vaporizer) is a device that converts liquefied natural gas (LNG) from liquid to gas.
LNG tanks are mainly designed in two forms: horizontal and vertical. Each form has its own advantages and disadvantages and applicable scenarios.
Since LNG storage tanks need to maintain extremely low temperatures, efficient insulation materials are considered during design to reduce heat transfer and evaporation losses.
Vertical cryogenic liquefied natural gas storage tanks are compact cryogenic liquid storage equipment with various equipment (valves, safety systems, etc.).
LNG requires the liquid storage tank to have good low temperature resistance and excellent cold preservation performance.
LNG tank welds must be 100% magnetic particle tested (MT) and 100% vacuum tightness tested (VBT).
By keeping the temperature low, LNG remains in a liquid state, thus avoiding the problem of pressurization.
The inner cylinder and pipeline materials of the 100m3 vertical LNG storage tank are 0Cr18Ni9 stainless steel, and the outer cylinder is 20R pressure steel.
Vertical LNG storage tanks are generally double metal wall structures, stored under pressure, and insulated with vacuum powder.
LCO2 (Liquid Carbon Dioxide) storage tanks are equipment specifically designed to store and handle liquid carbon dioxide.
LNG storage tank：Function: Store liquefied natural gas, usually a double-layer tank with high thermal insulation performance.
The cold insulation system is an important part of LNG storage tanks, including the cold insulation layer at the bottom of the tank, the cold insulation layer at the tank wall and the cold insulation layer at the ceiling.
